    Abstract: A method/system of mechanical holdowns allows a substrate sheet in a CBAM (composite-based additive manufacturing technology) process to lie flat during printing. The invention includes a process of mechanically clamping sheets to be printed by a print head to a flat platen using a set of barrel cam driven clamping fingers. The finger supports are attached to the platen and the fingers can be raised and lowered with respect to the platen. Each finger can rotate while swinging downward toward a sheet at the edge of the platen. To clamp the sheet, the fingers are rotated to the perpendicular position and swung lower down to pinch the sheet to the platen. The process can include additional steps that release some, but not all, of the fingers to allow the sheet to relax before re-clamping them.

    Abstract: A stacker component of an apparatus for automated manufacturing of three-dimensional composite-based objects for aligning registration of sheets. The stacker includes a sheet catcher; a frame having a base plate with the base plate having tapered registration pins to align a stack of substrate sheets. The registration pins are mounted in the base plate and project vertically to a location just below the sheet catcher. The stacker also has a presser with a press plate and a belt driver system that moves the press plate up and down allowing the press plate to exert downward pressure on the stack and a slide system with two guide rails that enable the base plate to be loaded and unloaded. A conveyor can be disposed so that after a substrate sheet exits a powder or printing system, the sheet is conveyed onto the sheet catcher.

    Abstract: A method, product, apparatus, and article of manufacture for the application of the Composite Based Additive Manufacturing (CBAM) method to produce objects in metal, and in metal fiber hybrids or composites. The approach has many advantages, including the ability to produce more complex geometries than conventional methods such as milling and casting, improved material properties, higher production rates and the elimination of complex fixturing, complex tool paths and tool changes and, for casting, the need for patterns and tools. The approach works by slicing a 3D model, selectively printing a fluid onto a sheet of substrate material for each layer based on the model, flooding onto the substrate a powdered metal to which the fluid adheres in printed areas, clamping and aligning a stack of coated sheets, heating the stacked sheets to melt the powdered metal and fuse the layers of substrate, and removing excess powder and unfused substrate.
